At the end of the Pleistocene period, approximately 12,800 years ago—give or take a few centuries—a cosmic impact triggered an abrupt cooling episode that earth scientists refer to as the Younger Dryas.

The sun's activity could be affecting a key ocean circulation mechanism that plays an important role in regulating Greenland's climate, according to a new study. The phenomenon could be partially responsible for cool temperatures ...

According to a new study published in Nature Geoscience, the Greenland ice sheet has been shown to accelerate in response to surface rainfall and melt associated with late-summer and autumnal cyclonic weather events.

The relentless flow of a glacier may seem unstoppable, but a team of UK and US researchers have shown that during some calving events - when an iceberg breaks off into the ocean - the glacier moves rapidly backward and downward, ...

In 2008 scientists from Woods Hole Oceanographic Institution (WHOI) and the University of Washington documented for the first time how the icy bottoms of lakes atop the Greenland Ice Sheet can crack open suddenly—draining ...

Operation IceBridge wrapped up its seventh Arctic deployment on May 21, when NASA's C-130 research aircraft with the mission's researchers and instruments on board departed Thule Air Base in Greenland and headed to NASA's ...

In northwestern Greenland, glaciers flow from the main ice sheet to the ocean in see-sawing seasonal patterns. The ice generally flows faster in the summer than in winter, and the ends of glaciers, jutting out into the ocean, ...

A new study shows how huge influxes of fresh water into the North Atlantic Ocean from icebergs calving off North America during the last ice age had an unexpected effect - they increased the production of methane in the tropical ...

The entire research station NEEM has been moved 465 km across the Greenland ice sheet on skis to the new camp EGRIP, where there will be a future international drilling camp and a gateway to research programmes in East Greenland.

A new study using evidence from a highly detailed ice core from West Antarctica shows a consistent link between abrupt temperature changes on Greenland and Antarctica during the last ice age, giving scientists a clearer picture ...
